The

flange 22, unlike theflange V19 is outwardly and downwardly curved to dispose the marginal edge thereof upon the upper surface of the"v flange 19 when the journal ends'23 of the ribs 13 are tobe locked .in position therewith. rljhe-curvature of the flange 22 will form a partial housing for thejournal ends of the ribs and prevent distortion thereofl when said ribsare extended and retracted from their respective positions.

Inasmuch as the ribs 13are to be extended inthe manner suggested in Figure1` ofthe drawings,.it is alsonecessaryto construct l. the flange22 in such manner that 'the radial slots k24% therein will be aligned with the 4slots in .the 'flangeA 19.
